With a price-to-earnings (or "P/E") ratio of 9x Pilgrim's Pride Corporation (NASDAQ:PPC) may be sending very bullish signals at the moment, given that almost half of all companies in the United States have P/E ratios greater than 19x and even P/E's higher than 34x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/E.

We've found 21 US stocks that are forecast to pay a dividend yield of over 6% next year. See the full list for free.

With earnings growth that's superior to most other companies of late, Pilgrim's Pride has been doing relatively well. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

What Are Growth Metrics Telling Us About The Low P/E?

Pilgrim's Pride's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Retrospectively, the last year delivered an exceptional 147% gain to the company's bottom line. The latest three year period has also seen an excellent 488% overall rise in EPS, aided by its short-term performance. So we can start by confirming that the company has done a great job of growing earnings over that time.

Turning to the outlook, the next three years should bring diminished returns, with earnings decreasing 8.5% per annum as estimated by the seven analysts watching the company. With the market predicted to deliver 10% growth per annum, that's a disappointing outcome.

In light of this, it's understandable that Pilgrim's Pride's P/E would sit below the majority of other companies. However, shrinking earnings are unlikely to lead to a stable P/E over the longer term. Even just maintaining these prices could be difficult to achieve as the weak outlook is weighing down the shares.

The Final Word

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

As we suspected, our examination of Pilgrim's Pride's analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
